Sea squirts. If you don't know what they are, go to any pier or look at pictures of reefs, they are the tubular potato shaped tubes you see clinging to everything! Now that you know what we're talking about, would you eat one? What if it could possibly reverse aging? Well a new study from Chinese and American scientist found that mice who were fed sea squirts regularly had signs of reversed aging in their cognitive functions and even the reverse of greying fur! I wonder if it could regrow my hairline.
